[FEATURE]: Keyboard command to jump to the next session with a pending permission request

[athal7]

Problem

When several sessions are running, an agent often blocks waiting for me to approve or deny a tool call. Today the only way to find that session is to scan the sidebar for the warning dot and click it. There's no keyboard way to get to it.

The existing session.next.unseen / session.previous.unseen shortcuts (⇧⌥↓ / ⇧⌥↑) cycle by unseen turn-complete/error notifications, not by pending permissions, and only within the current project — so they don't land me on the blocked session.

Proposal

Add a command (e.g. session.next.permission / session.previous.permission) with a default keybind that jumps to the next session that has an actionable pending permission request, ideally across all open projects, not just the current one.

Notes

The data and helpers already exist client-side: store.permission[sessionID] (packages/app/src/context/global-sync/types.ts), and sessionPermissionRequest(...) — the same predicate the sidebar warning dot uses (packages/app/src/pages/layout/sidebar-items.tsx). The implementation could mirror navigateSessionByUnseen (layout.tsx), swapping the unseen-count check for the pending-permission check.

[ai] Checked the keybinds docs — no existing binding covers this. The only permission keybind is permission.prompt.fullscreen. Worth noting this would fit the existing session-navigation model (session_child_cycle, session_parent, etc.), so it's a natural addition rather than a new pattern.
